To all whom it nutty concern:

Be it known that we, HARRY Milnnoon and Jenn if". KELLY, both citizens of the United States, residing at Trenton, county of Mercer, State of New Jersey, have invented certain new and useful improvements in Lavatory Basins; and we do hereby declare the followi in to be a full. clear and exact descri tion of also formed in the material the invention, snchas will enable others skilled in the art to which it appertaine tomake and use the same. The invention relates other lavatory-basius, and has for its particular object to construct such a basin having a scaling-trap formed integrally with the basin, and all the ports, pipes, inlets, and passages out of which the basin is composed instead of being made out of metal or other material dissimilar from that of the basin and attached or secured thereto. The invention is illustrated in the accompanying-drawings, forming part of this speci fication, wherehr- Figure 1 is a fragmentary view of the rear side of a porcelainlavatory-basin constructed in accordance with our invention, part-of the figure being cut away, so to show the interior construction of the overflow-pipe and the inlet connections for hot and cold water. Fig. 2 is a vertical cross-section of such a basin on the line a' a, 1; and Fig. 3 is a sectional plan on the line 1 1 of Referring to the views, 0; denotes the bowl, 7) the horizontal slab projecting outward from the upper edge thereof, and c the flange or curtain running around and extending down from the edge of the slab. The sealing-trap is best shown at 0?, Figs. 1 and i2. instead oi being separate from the basin, as usual, it is formed integrally therewith out of the material of which the basin is composed. it is located at the foot of a pipe (2, of ample dimensions, that extends vertically down from the slab at the back of the basin and is made integral with the slab and bowl. it opens rearwardly, as shown at f, Figs. 1 and 2, and the bowl communicates directly with it through the space g and the opening to porcelain, clay, or-

,t, controlled by avalve The bowl has also an indirect communication with the sealing- 5 trap through the pipe 0, this pipe having an uptake is and a downtake Z, separated from each other by a partition m, which divides the pipe into two pipes. The upper edge a of the partition is considerably below the upper edge of the basin a, so as to prevent the latter from overflowing. The pipes [13 and l constitute an open overflow communication from the bowl to the trap, and communication is made with the bowl and its overflow by means of the same opening g through which the water passes directly to the trap when the valve is lifted fromthe opening /l. The pipe 0 is made of largediameter in order that its two divisions 7 Z maybe large enough to per- 5 mit read y access thereto for cleaning. The pipe extends vertically along the rear side of the bowl immediately above the trap and has a large opening 0 through the slab at its upper end, so as to permit the hand or a brush 7 or cloth to be introduced for cleaning purposes, and the outlet-opening IL is located in line with the uptake k of the overflow in order that access may be readily had to the valve and the opening It. As will be seen in Fig. 2, the uptake is is a straight pipe Without grooves or bonds, and the downtake l is also straight and parallel with the uptake, both said passages being included in the pipe Z, and the opening at the top of the pipe being closed by a porcelain cover 1), which when removed exposes the whole interior diameter of ,both the uptake and the downtake and affords ready access to the'trap and all the outlet-ports and passages of the basin. I

In furtherance of the object of dispensing Vas far as possible with all metal fittings and separate parts the basin is provided with two inlet pipes r and s for hot and cold Water, respectively. These pipes are integral with the 9 basin, like all the other parts, and are preferably formedon the exterior of the pipe Z, at opposite sides thereofiand extend from a point preferably though not necegsarily about level with the exit from the trap upward to a passage t, which is formed in the ledge part way emission of solid water into the bowl.

The handle or knob has an extension passing freely and loosely through the opening in the cover p, and the valve-stem w,

which is connected to the extension, is continued down beyond the offset 11/ into a vertical guideway 1), formed in the partition in, so that the stem may be raised and lowered to operate the valve without being diseonnectet from its guide. The partition is preferably located centrally in the pipe 1;, so that the guideway for the valve-stern comes immediately under the central opening in the'cover p, and the offset a from the stem not only onables the valve 2 to be hung from a point centrally over the discharge-opening h, but cooperates with-the upper edge vi. ot' the partition m to form a means for holding the stem raised and the valve locked in open position. This is best illustrated in dotted lines in Fig. 1, where it will be seen that the valve-stem has beenlil'ted and given a partial turn to the right until the offset/1. overhangs and rests upon the upper edge of the partition in, the valve at this time hanging freely against the lower side of the partition above the opening /1, as indicated in dotted lines in the second ligure.

As before stated, the passage I, into which the upper ends of the hot and cold water inlet pipes 'r and s open, partially surrounds the opening to the pipe 13, forming a semicircular chamber, and the supply-oriiice to the basin is located in the center of this chamber, so that when one inlet-pipcisbeing used the opposite end of the chamber next the other pipe might form a sort of trap for the air and might cause the aspiration or hissing sound which is so objectionable inotherbasins. We therefore provide air-vents c c from the chaml'ier at each end into the upper end of the pipe so that any air which may happen to beentrappml in the chamber, well as any that may be carried along by the water, may lind a free vent into the overflow and permit the immediate Ye also prefer to form at the lower ends of the cover p, 3

Thisopens up the whole interior structure, permitting easy access to the trap, the up and down take of the overlion, and all the orilices leading to and from the bowl. I

Having thus described our invention, what we claim, and desire to secure, is"- l. in a porcelain lavatory-basin, the combination of a scaling-trap, an overflow leading from the bottom of the bowl to the trap, a discharge-opening leading from the bottom of the bowl directly into the trap, a water supply passage at the top of the bowl, a water inlet or inlets leading to said supply-passage, and a vent leading from the sup 'ily-passage to the overflow, all of said passages, inlets, openings with the basin out of the material of which it is composed.
